Abstract:In order to realize remote monitoring of the drilling process at each drilling station by the drilling headquarters, on the basis of the single station for automatic real-time drilling monitoring developed in the early stage, TIA portal software was applied to develope the master-slave station for drilling monitoring with Siemens1200PLC used as the master control equipment, and Siemens200PLC as the slave control equipment to monitor the drilling parameters at each drilling station. Master-slave controlling is realized through the configuration of the master control equipment and slave control equipment at each station. Internet was used to test transmission after the master-slave station was set up, and the results showed that internet can provide continuous transmission from breakpoint and short-distance transmission of real-time monitoring data on drilling.
